I copied/pasted pictures to my Drobo 5N. Now I have a "Thumbs" file in every picture folder that is on the Drobo. I don't have the Thumbs.db file in any picture folder on my desktop where I copied the pictures from.

Found out that the Drobo uses a EXT3 file system so files aren't hidden like they are in Windows. The Thumbs.db files can be deleted without any issues.
